(a) View of the dinuclear unit in the crystal structure of [Fe2(Hsaltrz)5(NCS)4]·4MeOH. (b) Temperature dependence of χMT versus T revealing a steep spin transition from [HS–HS] to [LS–LS] pairs. The tubes show the color change from yellow at room temperature to burgundy at liquid nitrogen temperature. The DSC response, shown in the inset, confirms that a first-order phase transition takes place on cooling and warming [235].
